APPENDIX C - SCPI COMMAND/QUERY DEFINITIONS

C.1

INTRODUCTION

This appendix defines the SCPI subsystem commands and queries used with the MBT Power
Supply controller. Subsystem commands are defined in PAR. C.2 through C.49, arranged in
groups as they appear in the tree diagram, Figure 3-4. Table C-1 provides a quick reference of
all SCPI subsystem commands and queries used in the Interface Card.

C.2

INITiate[:IMMediate]

COMMAND

INIT[:IMM]

Syntax:

Short Form: INIT:[IMM] Long Form: INITiate[:IMMediate]

Description: Enables a single trigger. If INIT:CONT is OFF, then INIT[:IMM] arms the trigger system for a single

trigger. If INIT:CONT is ON, then the trigger system is continuously armed and INIT[:IMM] is redun-
dant. This command enables a single trigger. A GPIB <GET>, *TRG or command completes the
sequence. Upon receipt of the <GET> or *TRG command, the power supply will return to the pro-
grammed values of voltage and current established by the VOLT:TRIG and CURR:TRIG commands.
After a GPIB <GET> or *TRG command has been received, subsequent GPIB <GET>, *TRG com-
mands have no effect unless preceded by INIT or INIT:CONT ON. Related Commands: <GET>,
*RST, *TRG. (See example, Figure C-3.)

C.3

INITiate:CONTinuous

COMMAND

INIT:CONT

Syntax:

Short Form: INIT:CONT {ON | OFF} or {1 | 0} ( 1 = on, 0 = off)
Long Form: INITiate:CONTinuous {ON | OFF} or {1 | 0} ( 1 = on, 0 = off)

Description: INIT:CONT ON enables continuous triggers.; INIT:CONT OFF disables continuous triggers. If

INIT:CONT is OFF, then INIT[:IMM] arms the trigger system for a single trigger. If INIT:CONT is ON,
then the trigger system is continuously armed and INIT[:IMM] is redundant. Executing *RST command
sets INIT:CONT to OFF. (See example, Figure C-3.)
